Cs doped tungsten oxide nanoparticles for producing smart glass are also known as cesium tungsten oxide nanoparticles, cesium tungsten bronze nanoparticles or CsxWO3 nanoparticles. And such a smart glass has high transparency and excellent near infrared shielding performance. It is reported that after being exposed to UV light for 30 minutes, the color of cesium tungsten bronze nano powder changes from the original dark blue to dark purple. It indicates that photochromism has occurred.

Cs0.32WO3, or cesium tungsten bronze, is a welcoming near-infrared shielding material as Cs0.32WO3 nano particles have been shown to manifest a strong absorption of near-infrared light. And therefore, cesium tungsten bronze is mainly applied to produce heat insulation coating and film for automotive and architectural windows.

Cs0.33WO3, as the most widely studied near-infrared shielding material, is attracting more attention from different fields including nano materials, energy saving buildings and heat insulation products for autos. Well, you know, there are many other heat insulation materials such as LaB6, ITO and ATO. How about the heat insulation effects of Cs0.33WO3, LaB6, ITO and ATO?

As a new type of near-infrared shielding material, CsxWO3 (cesium tungsten oxide) has selective and strong near-infrared absorption in the range of 800 to 1200 nm. And it is reported that cesium tungsten oxide diminishes near-infrared rays of shorter wavelength which has much of the heat energy in sunlight compared to ITO (tin-doped indium oxide) and ATO (antimony-doped tin oxide).
